SPECIFICATION forming part of Letters Patent No. 390,562, dated October 2, 1888.

Application filed October 1, 1886. Serial No. 215,061. (No model.) .Iatented in Germany March 5, 1887, No. 40,988; in France May 5, 1887 No.183,356; in Belgium May 20, 1887, No. 77,530, and in England June 25, 1887, No. 9,045.

To all whom it may concern.-

Be it known that I, OSCAR BRUNLER, of the city, county, and State of New York, have invented certain Improvements in Apparatus for Charging Liquids with Carbonic-Acid Gas, (which has been patented to me or to my authorized agents in Germany, No. 40,988, dated March 5, 1887; in France, No. 183,356, dated May 5, 1887; in Belgium, No. 77,530, dated May 20, 1887, and in England, No. 9,0l5,datcd June 25, 1887,) of which the following is a specification.

This invention relates to an improved apparatus for charging fermented and un fermented liquids with carbonic-acid gas, the object ofthe invention being more especially to charge beer with carbonic-acid gas in place of subjecting the same to a second fermentation by means of kraense, the carbonic-acid gas assisting in clarifying the beer, while impregnating it at the same time.

Attempts have been made heretofore to charge beer while in the shavingscasks with carbonic-acid gas; but these attempts have failed, owing to the fact that the porous nature of the wood from which the casks are made permits the escape of the carbonic-acid gas and. prevents the use of high pressu resin charging the liquid with the gas. The escape of the gas is caused mainly for the reason that a certain space is required for the introduction of gas at the upper part of the cask, the surface of which dries out by the contact of the gas and permits thereby the gas to escape. To overcome this defect and carry out successfully the impregnating of beer in the shavings-casks in place of mixing it with kraeuse, I arrange in the cask a bell-shaped reservoir, which is supported in any suitable manner at the interior of the cask and connected by a supplypipe with a suitable source of carbonic acid. The bell-shaped reservoir is submerged in the beer or other liquid to be treated, the liquid forming a hydraulic seal for the reservoir. The supply-pipe is provided with a stop-cock to regulate the supply of gas, and the top of the cask provided with an air-escape pipe having a stop-cock.

The accompanying drawing represents a side elevation, partly in section, of my improved apparatus for charging liquids with carbonicacid gas.

A in the drawing represents a cask, which is supported in any suitable manner and provided with asuitable gage-glass, a, properly connected therewith. At the interior of the cask A, and preferably at the top of the same, is supported a bell-shaped gas-reservoir, B, the lower edge of which is submerged into the liquidin the cask; or, in other words, the level of the beer is above the lower edge of the reservoir A, so that a space, (1, is left above said level at the upper part of the cask.

The receptacle B is connected by a pipe, 0, with any suitable source of supply of carbonic acid. As shown in the drawing, this source of supply consists of a receiver, D, containing liquid carbonic acid, said receiver being provided with a pressure-reducing valve, E, of any approved construction. The pressurereducing valve E regulates the pressure under which the gas is permitted to pass through the pipe 0 into the bell-shaped reservoir B. The pipe 0 is provided with a suitable stop-cock, e, by which the pipe may he opened or closed at will, and with a cheek-valve, f, by which re gurgitation from the cask A is prevented.

In place of the receiver D may be substituted a reservoir containing compressed carbonic-acid gas, or a generator in which carbonic-acid gas is produced in such rapidity and under such pressure as may be provided.

The cask is further provided with the usual racking-oif faucet or valve, 9, at its lower part, and with an air-escape pipe, h, having a stopcock, h, at its upper part, so that the air may be expelled from the space (I to the outside of the cask while the carbonicacid gas is intro duced into the cask.

During the operation of charging the liquid in the cask the faucet g and air-escape pipe h are kept closed, the latter being kept open long enough to permit all the air to escape from the space cl. Then the liquid is to be charged with carbonic-acid gas, the stop-cock e is opened and the gas supplied to the interior of the reservoir B, the pressure of the gas on the surface of the liquid producing the lowering of the level inside of the reservoir and the rising of the same outside of the same until it fills entirely the space cl. This is readily observed at the air-escape pipeg as the liquid begins to flow out of the same. The cock h of the escape-pipe is then closed. The lower edge of the reservoir B has to be submerged far enough in the liquid so that it can never rise out of the same, theliquid formingahydraulio seal for the space inolosed between the wall of the reservoir and the surface of the liquid. The gas is now brought in contact with the liquid to be charged, and gradually absorbed by the same. By leaving the liquid in contact with the gas for a certain length of time the same is impregnated to the required extent, While no gas can escape through the walls of the cask.

The invention is specially adapted for charging liquids in Wooden casks, as only in such casks the objections hereinbefore referred to are experienced. The apparatus is also applicable for charging still-wines with carbonicacid gas, and also to any other liquids, fermented or unfermented.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Thecombiuatlon, witha cask, of an open bottomed bell-shaped reservoir arranged at the interior of the cask in such a manner that its lower edge is submerged in the liquid, a receiver containing carbonic-acid gas under pressure, and a gas-supply pipe connecting the receiver with the reservoir, substantially as set forth.

2. The combination, with a cask, ol'an openbottomed bell-shaped reservoir arranged at the interior of the cask in such a manner that its lower edge is submerged in the liquid, a receiver containing carbonic-acid gas under pressure, a gas-supply pipe connecting the receiver with the reservoir, and an air-escape pipe applied to the top of the cask and provided with a stop-cock, substantially as set forth.
